title: Prospective clinical evaluation of a new manometer syringe that distinguishes pressures below 30 and above 50 mmHg.
abstract: OBJECTIVE
  To evaluate a new disposable syringe (Certofix PresSure Check [B Braun Melsungen AG, Melsungen, Germany]) that serves as a manometer.
  
  
  METHODS
  Prospective study.
  
  
  METHODS
  University hospital's cardiac surgery suite.
  
  
  METHODS
  21 consecutive patients with continuous invasive monitoring of central venous and arterial pressures during cardiothoracic surgery.
  
  
  METHODS
  The Certofix PresSure Check syringe was connected to the side port of the central venous and arterial catheters.
  
  
  RESULTS
  Central venous pressures were correctly indicated as below 30 mmHg and arterial pressures as above 50 mmHg in all 21 patients.
  
  
  CONCLUSIONS
  Certofix PresSure Check provides a unique way of testing whether a catheter is placed in a low or high pressure system. It can be used for identifying inadvertent arterial punctures.
